[2019] Is Gunsmith - part 5 Broken?

On modding the Dsniper rifle i have not been able to reach the ergonomics requirement. i tried to build it in presets after examining all its mods and after pulling my hair out i looked at the wiki. i had all the mods and the exact same gun as was displayed, but the ergonomics were only 35 and not 39. a friend told me that the scope seems to have been altered and now gives -8 ergo instead of -4.
